“…In the case of attributebased signatures (ABS), users obtain from an authority their secret keys as a function of the attributes they hold, with which they can later sign messages for any predicate satisfied by their attributes. Another related notion to ABS is fuzzy identity-based signature which was proposed and formalized in (Shanqing; and Yingpei [42]; Yang; et al [43]. It allows a user with identity ω to issue a signature which could be verified with identity ω' if and only if ω and ω' are within a distance judged by some metric.…”

“…As a similar notion to ABS, fuzzy identity-based signature was proposed and formalized in [21,22], which enables users to generate signatures with part of their attributes. To achieve the same goal, the notion of attribute-based signature was given in [2], but Tan et al [23] pointed out that this scheme is vulnerable to the partial key replacement attack. Moreover, in these works, authors do not consider any notion of privacy, resulting in leaking attributes used in producing signatures to the verifier.…”

“…ABS was proposed in [1,2], where users cannot forge signatures with attributes they do not possess even through colluding. Although the scheme in [2] reveals the set of attributes satisfying the policy, subsequent research of ABS offers an attribute-signer privacy guarantee for the signer, that is, a legitimate signer remains anonymous without the fear of revocation and is indistinguishable among all the users whose attributes satisfy the policy specified in the signature.…”

Attribute-based signature (ABS) is a new cryptographic primitive, in which a signer can sign a message with his attributes, and the verifier can only known whether the signer owns attributes satisfying his policy. Moreover, the signature cannot be forged by any user not having attributes satisfying the policy. ABS has many applications, such as anonymous authentication, and attribute-based messaging systems. But these applications may require a user to obtain attributes from different authorities, which calls for a multiauthority ABS scheme. In addition, multiple authorities can distribute the trust to all authorities, instead of concerning on a single attribute authority. In this paper, we propose a multi-authority ABS scheme, supporting complex policies, expressing AND, OR, and threshold conditions. We use a central authority to assure the usability of attribute keys a user getting from different attribute authorities. To prevent collusion attacks, we adopt a unique global identity (GID) for a user to bind his attribute keys and identity together. And a secret key from the central authority help the verification be independent of the user's identity. So our scheme can fit the requirements of real applications, and also distribute the trust to all authorities in the system.

Abstract. An attribute-based signature (ABS) is a special digital signature created using a dynamic set of issued attributes. For instance, a doctor can sign a medical statement with his name, medical license number and medical speciality. These attributes can be verified along with the signature by any verifier with the correct public keys of the respective attribute issuers. This functionality not only makes ABS a much more flexible alternative to the standard PKI-based signatures, but also offers the ability to create privacy-preserving signatures. However, none of the ABS constructions presented in the literature is practical or easily realizable. In fact, to the best of our knowledge, there is currently no ABS implementation used in practice anywhere. This is why we put forward a new ABS technique based on the IRMA attribute-based authentication. IRMA already has an efficient and practical smart-card implementation, and an experimental smart-phone implementation too. They are currently used in several pilot projects. In this paper, we propose an ABS scheme based on the existing IRMA technology, extending the currently available IRMA devices with ABS functionality. We study the practical issues that arise due to the introduction of the signature functionality to an existing attribute-based authentication scheme, and we propose possible cryptographic and infrastructural solutions. We also discuss use cases and implementation aspects.
